Not to be forgotten about in the hullabaloo surrounding the launch of the PS4 and Killzone: Shadow Fall, Guerilla Games has outlined its plans for future updates to the PS Vita's Killzone: Mercenary. Over the next few months, the portable first-person shooter will receive a number of updates, one of which will introduce two new maps.

Update 3 will be the first to arrive sometime in the next few weeks. "In terms of functionality there will only be minimal changes, but this is the patch that reduces the size of the other patches!" Guerilla Games explained. "After installing this patch it will free up around 800MB of space for those who have already installed Updates 1 & 2."

Following that will be Update 4 in January. This is being designed to improve Matching and help reduce join-game connectivity problems. It will also add an auto team-rebalancing feature.

Update 5 is considered the "big one," and will add two new multiplayer maps for free. Niether of the maps were named, but Guerilla Games shared screenshots teasing both of them. This update will also include the release of offline Botzone for Mercenary and Guerilla Warfare modes.

Update 6, the last one detailed by Guerilla Games, will arrive in the first few months of 2014. It will contain "continued refinements" along with support for playing Killzone: Mercenary on Vita TV.

As always, we'll be sure to keep you updated once all the patches are detailed in full and released.
